10. According to the first law of thermodynamics, the energy of the universe is constant. Does this mean that AE is always equal to zero? a. Yes, AE = 0 at all times, which is why 9 = -W. b. No, AE does not always equal zero, but this is only due to factors like friction and heat. c. NO, AE does not always equal zero because it refers to the system's internal energy, which is affected by heat and...
